ABSTRACT:
A system for forcefully igniting a spray of fuel injected into combustion chambers of a diesel engine during engine starting, in place of a conventional glow plug preheating system. The system comprises a plurality of spark plugs located within the respective combustion chambers of the diesel engine and an ignition means for sequentially igniting each of the spark plugs. The system is operated simultaneously with an engine starter motor and at least until the engine has achieved a spontaneous ignition state or most preferably until a fixed interval of time after the engine has achieved the spontaneous ignition state. Detection of the spontaneous ignition state is based on (a) combustion pressure; (b) engine speed; (c) oxygen concentration; (d) engine starter motor actuation (e) exhaust gas temperature; or (f) engine cooling water temperature.
